Ben Dovers production company has been involved in a campaign of "speculative invoicing", where they send out letters, initially through lawyers, to alleged copyright infringers demanding a payment of £700 or face potential court action. The company paid for a list of alleged BitTorrent file-sharers identities, and retained the services of Tilly Bailey & Irvine to pursue the alleged copyright infringers for compensation, using what it claims to be "bespoke technology which captures the irrefutable evidence of the perpetrators". It was revealed that this technology, designed by physicist Clement Vogler of computer consultants Ad Litem Limited, a company which was dissolved in 2011, was targeting innocent individuals, and that the speculative invoicing relied on the embarrassment of those targeted agreeing to the fine to avoid the threatened court action, regardless of whether they were guilty or not. Following adverse public and press reaction, Tilly Bailey & Irvine abandoned the practise and accepted a £2,800 fine from the Solicitors Regulation Authority. Without the aid of solicitors, Golden Eye (International) Limited continued the practise of speculatively invoicing those they claim had "infringed their copyrights".
